"Blue Hat" isn't a term, there is "black hat", "white hat" and "grey hat". The term "blue hat" simply comes from the quite popular blackhat blog, bluehatseo.
blue, yellow, green or whatever color if you want to wear an SEO hat i would suggest you choose black, white or both. those are just new terms and gimmicks confusing people.
Mmmmhhhh! I am confused. I have read all the answer but I still don't know what would be a black, white or blue hat SEO. Thanks for the confusion.
Blue Hat is similar to Black Hat SEO. Blue hat has some more advance techniques. But I would prefer White Hat SEO than any other SEO.
Same thing as all of the above statements...it's like a hacker calling themselves a super hacker...they do the same stuff.
Blue hat is clean and honest seo. You can include onsite page optimization, article directory submissions and directory submissions. Anything that is clean and not spammy
